The US is home to more billionaires than China, Germany and Russia combined

There are 2,604 billionaires in the world, according to the Wealth-X Billionaire Census 2019, and over a quarter of these ultra-high-net-worth individuals reside in the U.S. "North America was the only region to record an increase in billionaire population," the report notes.

While the worldwide billionaire population was down 5.4% in 2018, it grew by almost 4% in the U.S., from 680 to 705 individuals, the report found. China, the country with the second-highest number of billionaires, has 285.
